.To.aZZ whom. it may concern.- v Be it known that we, JOHN J. NOLAN-and JAMES W and useful Improvement Loom-ShuttleoxesQof is a specification. The object of our invention is to provide -m cans. for preventing the yarn of theshuttles in the raised sh uttle-boxes from being drawn .into' the shedwith the yarn of the outgoing shuttle; to prevent the straining. or breaking of the yarn by engagement between the sideof' the traveling shuttleand the side of the shuttle box mouthpiece and toforce consists m the improved eonstructlon of the mouthpiece,-and in the combination therewith of a friction-cushion as hereinafterfully set forth.

In' the accompanying drawings,'Figure .1 represents afront side view of the shuttleboxes and the mouthpiece with a portion of the lay-beam. Fig. 2 represents a vertical section taken in the line 2 2 of Fig. 1, showing a front edge view of the mouthpiece. Fig. 3 represents an enlarged front edge view of the mouthpiece. Fig. 4 represents an enlarged rear side view of the same. Fig., 5 represents an enlarged top view. Fig. 6 represents a'horizontal section taken in the line 6v 6 of Fig. 3. In the drawings, A represents the lay-beam 5 B, the reed; C, the loom-temple, and- D the line of' the web. The 'monthpiece-Eis provided with a'recessed lip f, which serves to guide then-p-and-down' movement of .the forward edge of thedrop-shuttle boxes at a,' in which theshuttles are held by the shuttle-binders b b, the .said shuttle-binders being actuated by means of thespringscc. The rearedge of the'shuttle-boxes is guided in its up-and-down' movement by the plate E, which is secured to .the armH extending outward from the lay-beam A. The mouthpiece. E is secured to the lay-beam A by means of the bolt d and tothe upward extension e of the la -sword -I by means of the bolt 9, the curved surface-h of the Ilniteihthe shuttle.

I ofthe rear arm tot the mouthpiece serving to guide the nose of the shuttle into its shuttle-.box,'and the inclined surfacej of the said .arm servi the sh utt pletely in ng. upon the upward movement of le-boxes to force the shuttle comto its box, in case it has not fully entered the same from the shed, thus preventing the liability of accident to the shuttlebox mechanism, ,andthe upright plane surface 0 of t endwise forward fromthe raised boxes.

he said arm iserves to prevent the movement of the shuttles The arm 2" of the mouthpiece E is offset backward from the attaching-ear Z in the dithe line of the 1ay-beam, so that rection of the extreme inner surface is at the lower pertion of the offset-arm 1," will only bear against the shuttle when the shuttle is close up to the shuttle-box, and the backward position of the said bearing-surface serves to prevent the.

yarn from the shuttles in the raised shuttleboxes from being caught and broken between the inn-er surface of the mouthpiece and the 7 side of the traveling shuttle, and the yarn is prevented from being discolored by contact with the outside of the shuttle, as'in the 'mouthpieces heretofore employed. Another WILKIE', or PAwTUcKE'r; RHODE ISLAND.

advantage of this construction consists in the saving efiected in the wear of the shuttles. The striking side of the end of the shuttle when passing through the ordinary shuttlebox mouthpiece ,is liable to engage with the forward edge sf the shuttle-box, whereby the end of the shuttle becomes .WOllIb and splintered, so t hat in a few months it becomes use less, whereas when the bearing-surface of the shuttle-box mouthpiece .is offset from the I attaching-ear Z, so as to carry thebearingsurface farther than heretofore toward the mouth of the acting shuttle-box, the shuttle is prevented from coming in contact with the forward end of the shuttle-box and the lasting qualitiesof the shuttle are increased.

To the inner side of the upright arm 7:. er the mouthpiece E which extends above the line of th e acting shuttle-box, is secured the friction-cushion J, preferably made of a strip of felt or woolen cloth,

the threads of yarn n, which extend from the selvage m of the woven web serving to support D at theloonirod temple 0 to the several shuttles in the raised shuttle-boxes a a, and when the yarn is 50 supported by the cushion J it will not be drawn into the shed by entanglement with the yarn of the out-going shuttle.

By the use of our improvement the selvages of the web may be woven in a perfect manner, so that the trouble and expense of repairing the selvages as heretofore is avoided.

We claim as our invention- 1. The combination of the lay, and the drop shuttle-boxes, with the shuttle box mouth piece having an extension above the line of the top of the acting, shuttle-box, and the friction cushion arranged in the upward extension of the mouth piece, to prevent the yarn in the shuttle boxes from being drawn into the shed, substantially as described.

2. The combination of the lay, and the drop shuttle-boxes, with the shuttle box .mouthpiece having an extension above the line of the top of the acting shuttle'box, the said upward extension being provided with the inclined surface j, adapted to force the shuttle completely into the shuttle box, and the upright surface 0, adapted to retain the raised shuttles in the shuttle boxes, substantially as described.

3. The combination of the lay, and the drop shuttle-boxes, with the shuttle-box mouthpiece provided with the attaching ear l, the offset upright arm 11', adapted to guide the forward end of the shuttle boxes, and having an inner bearing surface It at the lower portionof the offset arm, near the month of the acting shuttle-box, substantially as described.

4. The combination of the lay, and the drop shuttle-boxes, with the shuttle-box mouthpiece provided with the attaching ear I, the upright arm '5', offset toward the boxes in the direction of the line of the lay beam, the inner bearing surface 75 at the lower portion of the offset arm near the mouth of the acting shuttle-box, and the friction cushion J arranged above theline of the top of the acting: shuttie-box, substantially as described.
